how to stop onChange method from being called on every key press (call it only once by first key press) ?

Answer 1

Set a variable to control it.

var pressed = false;

Then, change the variable to true after first key press. Perform the actions only if the variable is false.

if (pressed == false) { /* do action here */ }
